NUT-BOX.

Specification of Letters Patent No. 14,011, dated January 1, 1856.

'To aZZ whom it may concern Be it known that I, RICHARD H. COLE, of thecity and county of St. Louis, in the State of Missouri, have invented anew and Improved Adjustable Nut-Box or Die-Box for Nut-Making Machines;and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, Figure l being a front view of anut-box for forming four-sided nuts; Fig. 2, a front view of a nut-boxfor forming six-sided nuts, and Fig. 3 a section in the line -y of Fig.l.

The movable segments c, c, which form the sides of the nut box, areplaced in a cupshaped case which has a perforated bottom, A, in theaccompanying drawings, indicating the bottom, and Z, the rim of saidcase. The segments c, c, are adjusted and secured in any desiredposition within their inclosing case, by means of the eccentrics CZ, (Z,and the respective set screws e, e, f, f, and g, g, as represented inthe drawings. rIhe eccentrics (Z, (Z, are received within apertures inthe segments c, c, and the set screws e, e, pass through said eccentricsand enter screw apertures in the bottom of the case. The inner ends ofthe set screws f, f, which pass through the rim Z, of the case, bearagainst the curved outer surfaces of the segments, and the screws g, g,bear against the project-ing wings of said segments. The segments c, c,have projecting Hanches h, Zz, at their inner edges, one or all of whichmay be so faced with steel as to form cutting inner edges.

In the four sided nut-box for forming square nuts, the flanch of thesegment on the side that the bar is fed in at, must be armed with acutting inner edge. A portion t, of the lanch of the upper segment, anda portion o, of the right hand segment of the four sided nut-box, shouldproject beyond the faces of the flanches of the other segments, for thepurpose of grinding and directing the bar to its proper position infront of the nut box, as it is fed into the machine supplied with saidbox.

In the six sided nut-box, four of the anches of the segments must bearmed with cutting edges, viz: the two standing in oblique positions atthe left hand side of the box, and the two flanches standing in obliquepositions at the right hand side of the box. The width of the bar to beconverted into six sided nuts, must be just equal to the space betweenany two parallel sides of the nut-box. In the six sided nutbox, o, is aprojection from the Hanch of one of the segments on the right hand sideof the aperture in the box for the end of the bar to strike against whenit is fed into the machine, and Z, is a projection from the fianch ofthe segment at the top of the aperture in said box, which serves as aguide for the upper edge of the bar to strike against as it is fed in,opposite the mouth of the box.

It will readily be perceived that by loosening the respective setscrews, the position of the eccentrics CZ, fZ, can be so varied as toenlarge or diminish the size of the aperture in either the four sided,or the six sided nutbox, and then by tightening the respective setscrews, the segments c, c, can be firmly secured in the desiredposition. This principle can be applied in constructing nut boxes forthe formation of nuts of any desired number of sides.

My improved adjustable nut box can be secured in its proper positionwithin a machine, by means of set screws passing through the aperturesj, y', into the breast plate of the machine.

Having thus fully described my improved adjustable nut-box, what I claimtherein as new and desire to secure by Letters Patent, is-

The arrangement of the segments c, c, the eccentrics d, (Z, and the setscrews e, f, and g, with each other and with the case A, Z,substantially in the manner and for the purpose herein set forth.

The above specification of my improved adjustable nut-box, for nutmaking machines, signed and witnessed this third day of October A. D.1855.

R. H. COLE.
